Abstract:

This investigation means to develop the artificial propagation of Mastacembelus armatus. We used gas chromatography to determine the composition and content of fatty acid in sex gland, hepatopancreas and muscle of the wild male and female during breeding season. The result showed that the highest of SFA and MUFA in various tissues of male and female Marmatus were C16:0 and C18:1n-9; The maximum PUFA in various tissues of female and the hepatopancreas muscle of male was DHA, which appeared C22:4n-6 in the testis. The hightest content of fatty acid in the ovary, hepatopancreas and muscle of female accounted C18:1n-9(32.65%), DHA(18.54%), C18:1n-9(34.99%), respectively. The maximum fatty acid in the testis, hepatopancreas and muscle of male were separately C22:4n-6（33.52%）, DHA（45.68%）, C18:1n-9(23.24%). Therefore, we can cultivate the M. armatus by putting them in 2 different pools: one for female, and the other for male; if the C18:1n-9, DHA, ARA are to be added into the female fodder, we can promote the development of ovary and improve the quality of ovum; while adding the DHA, C18:1n-9, ARA and C22:4n-6 to the male fodder, we can improve the quality of sperm.
